7o all flu/wm z't may concern.'

Be it known that I, VAL'i-En VVmoHT, a citizen of the United States, residin in New York city, in the county of -New ork and State of New York, have invented certain new and useful lmproven'icnts in Combined Type-triting and Computing Machines, of which the following' a specification.

This invention relates to a new and imw proved computing,r head support, and is an improvement on my pending application No. 574,813, filed August 1, 1910.

In said application is disclosed a totalizer comprising a master wheel which is intermittently connected to travel step by step with the typewriter carriage, being released at intervals and again caught up by the carringe during` one traverse of said carriage, thus permitting' said totalizcr to be used for cross adding.

In said application the master wheel forms part of a computing carriage, which is attached 4to one end of a leve-r pivoted intermediate its ends in such a way that the opposite end of said lever, by means of a hook attached thereto. will be caught by tabulating stops settablc on the typewriter carriage and carried along thereby until the end of a computing column is reached.

After the end of such a column :is reached, said hook is freed from the tabulating stop which has been carryingr it along, and a spring automatically draws said master Wheel to the left-hand end of the totalizcr ready to begin computing;r in a new column.

Sometimes it is desirable to use such a cross totaiizcr in combination with a fo0ting totalizer extendingl the Whole length of' awriting line, which footing totalizer may be utilized as though it were a group of small, separate, footing totalizers.

Such a combination of cross and footing` totalizcrs is shown in my co-pending application 485,046, filed March 22, 1909; and if the number of computing 4wheels in each group used as a smallfooting` totalizer is at least as great as the number of computing wheels in the cross totalizcr, the mechanism set forth in my said application 574,813, filed August 1, 1910, will cross-add the items in said footing totalizer correctly.

If, '.however,4 the group of computing Wheels used as a footing totalizcr at the extreme left-hand of thc footing totalizer is smaller than the number of wheels in the cross tota-lizer, the masterwheel of ithe cross totali/.er would at times engage with the h-ighestlcomputing wheel in Said cross totalizer, While the footing master wheel was engaged with thc highest wheel of a small footing tot-alizcr having a. less number of wheels, with the result that one totalizer, for example, might register l 7 in its hundreds Wheel, Whereas the cross totalzer might register 1 in its trillions wheel. It

is obvious that such a condition of affairs would produce a complexity of errors in cross adding, which could not be disentangled. The present invention provides means whereby such errors are automatically prevented. If it is desired, for example, to utilize the three lettcr-spaces or computing wheels at the extreme left-hand of the footingr totalizcr as a. small footing totalizer of which the items are cross-added into the cross totalizer, a stop is pla-ced in the third space on the tabulating rack bar,-

returned to begin a neur line of writing,

said latch may catch the cross-adding carriage and carry it back so that the crossadding master wheel engagesmomentarily the lowest computing` Wheel of its ,totalizen At that moment, the cross computing carriage may be released, thus permitting said computing carriage automatically to bring said masterwheel toward the left-hand computing wheel. f

Where this latch 'is used for the crossadding master lwheel in a machine ofthe type' shown in my aforesaid application 574,813, the release of thlatch permits'the master, wheel to automatically return to engage the left-.hand cross computing'wheel.

This return movement is arrested ifacol umn stop is placed to catch the'maister' wheel at a point intermediate travl. If ,said stop has been placed in the third letterspace and the three left-hand :wheels-,ofthe 'footing totalizer are jaltilizedma's -a "small highest orV "Ico footing 'totiilizere any digit registered in the highest or hundreds computing 'wheel of said small totzilizer will be registered in the hundreds coml'nitiiig Wheel -of vthe cross totalize'r. A fter. haring (lone cross nddition und footing in this column, the master wheel is relenscd :is usual und caught by the next stop.

'-oolumn of numbers. und before the next number or column of numbers, so as to start with the highest denomination of the next number; the action being' controlled by tabular stops, as described in my said pendngnpplication 574,813.

On the return of the carriage ut the end of a line,.the continuitr of the action of .this connection is interrupted, that is to say, it resets the movable portionof the cross computing Vinecluinism ortotalizer the -full distance instead of a partial distance,

so that .the lcarriage loses accurate control of the totalizer or crossoomputing .mechanism, and i-t is. necessary to'space up to the desi-red point before stri-king a numeral.

.,.Tlze means provided .-in' this case to utilizethe full -length of the typewriting line without :a space at the beginning, causes or enables Vthe connection between the carriage and the totalizer to recover its accurate control of the relative position of the muster 'wheel and the computing wheels. This is done by utilizing t'ne return movement of -the carriage to manipulate certain 'portions of 'the cross computing mechanism or totalizer a. full ineifective or passive stroke, so asto enable a properly placed tubular Stop t0 ctch the. connection on 4the -:Lutoniatc resettherco'fL after Vthe ineffective stroke, at a point corresponding to the cle- .nomination .column in which it is desired to compute. y.In this case thereis show-n' :i connection between the ,carriage und Vthe cross computing; mechanism or totalzer, which is inoperative to connect the totaihzer .to the carriage .on the lletter-faciling movement of the carriage, but operative on the return movement'of the carriage vto operatively connect fthe two, so that certain portions of y -the cross 'computing mechanism or totalizcr This ooncan -be operatori by .the carriage.

automnrtic to the .further nectlon may be .extent that it will automatically be discon` meoted after it has accomplished the ,passiv-c or ineffective stroke, so thut .the resetting In the'embodiment 'used -to .ihn-strate this invention` the moin computing mechanism or footing or siilrtotailizcr, which is cnrr-iod with the carri-nge, is shown to curry u portion of the iirtei'i-nittent connection betwccn the carriage and the cross computing mech-.mism or totnlizcr, so that it may be said tlnit one computing mechanism is nianipulntec'l from the other computing mechunism.

1F ig. 12 is-a fragmentary front View in` lerated at every key stroke, being omiited.

The rack-10 is hung on arms 13, so that it may be lifted from the carriage.

Tabulator keys 14 are mounted upon levers 15, which, at their rear ends, raise the stop rods 16, having decimal stops 17 at their upper ends. Thesestops may coperate with interchangeably adjustable column stops 18. of the ordinary type-said column stops being inserted= as required, in notches '19, 20, formed in the top and bottom of a bar 21, which is fixed to the carriage (i.

Eachdecimal stop-rod has a shoulder 22 coperating with a universal `bar 23, which rocks about a pivot 24, and has an arm 25,

.which draws down a link 26 and vibraties a lever-27, `the latter fulcrumed at 27* and carrying a roll 27" to run upon the under 'Side of the rack bar 10, and lift thelatter from the escapement pinion 11, whenever a key 14 is depressed.' As so far described in detail, the partsare in common use on said Underwood typewriting machine.

The cross computing mechanism or totalizer' 80 includes a drive shaft 28, having a bevel pinion 29 meshing with a pinion 30 .upon a' square shaft 31, the latter being 'splined to a master-wheel 32, which moves jalong the shaft and has spurs or teeth 33 to A engage an internal set'of teeth 34 formed upon agang 'of-computing wheels 35, the lat- 'ter mounted in' a casing 36 and also having 'exterior teeth 3T `to mesh with gears 38, the .latter having number "wheels 39. The master-wheel32 is swiveled in a traveling hol- 'low mandrel 0r arbor 40, within which the' master-wheel shaft 31 may project, the

swivel-joint being shown at 41, and permitting the master-wheel 32 to be rotated by the shaft'l, while said master Wheel is caused to travel .in axial direction by themandrel or arbor 40.

The .mechanism so far described in detail forms no partof the presentinvention, and

' 4the drive.shaft:28'may be driven and controlled either. directly by the numeral keys 1 orjn any other suitable manner, as for instance in the manner set forth in my pending a plicat'ion No. 569,502, filed June 29, 1910. ince the driving means for said shaft form .no part 'of the present invention, it is deemed unnecessary, to illustrate the same. The, shaft, it will be understood, is rotated automatically upoli'the depression of any of the numeral keysjl, the extent of rotation del pending upon-which key is depressed.

the pinion 11 to release to the lever 42.

passes. through a longitudinal perforation The mandrel 40 is moved endwise by means of a forwardly and rearwardly extending lever 42, pivoted midway of its i ends by means of dgeons 43, so as to swing in a horizontal. p ane. At its forward en the lever is slotted at 44 toengage a pin 45` projecting from the carriage which carries the mandrel 40; said carruge comprising a. tube 46 sli ding upon ya vfixed rod 47, and also au arm 48, sliding upon a fixed horizontal rod 49; the mandrel-40'being secured to the forward end of the arm 48 by means of a set` screw 50. The movement of the mandrel 40 is o'l. course only suiicient to enable the master wheel32 to travel the length of the 'ang of computing wheels 35, one 0f whic is provided foreach number wheel 39. The rod 47 cooperates with two similar rods or studs 47 and'- 47", all rojectingfrom a framework plate or bra et 4 7, to carry a small plate 47", which also supports the end of rod 49. It will be seen that 4 7 and 47', Fig. 1, carry the casin 36.

At its rear end, the lever42 has a. slot 51 to engage a pin 52 projecting down from a slide 53. the latter carrying the stem 54 of a hook 55, adapted to engage lugs 56 formed upon said stops 1.8 or upon tappets or blades 5 7 which are forked to iit into the double rack 19, 20, -or oonnectin the paper carriage 6 to the master whee- 32 to cause the latter to travel step-by-step with the paper carriage,

The slide 53 works in a tubular guide or housing 58, which is slotted on its under side at. 59 to permit the pin 52 to ass down The stem 54 o the liok in the slide and is adjustablysecured to the.' latter by set screws 60,- Fig. 2. This permits slight longitudinal adjustment 0f the hook in order to' enable the master wheel 32 to be adjusted properly relatively to the computing wheels 'while the hook .is ell- A raged by one of the lugs 56. .The rack 21 ias at 60* the-usual provision for longi- .tudinal adjustment. The slide 53- llas a feather 61, to fit into the slot 59,'ftopre- 'vent the slide and the h'oolr from turning in' the tube. f

'lhe hook has a notch 62 toj enable it to engage any of the lugs 5.6. T he hook normally springs up to engage the adjacent lug.

For thiszpurpese the hook may be .made resilient or flexible', anda compressionspring 63 may be employed to' aid or cause thenp- Vwardmovementfofihe hook; said spring housed in a boss 64,' and confined by a screw 65, and pressing a' plunger 66 up against a straight portion of the underside of,4 the hook, thus holding the latter up while ermit-ting it trfrnove freclyendwise. -Il`he 'is vertically slotted-,gat 68. to form 'a guide plug to close lthis end of' the tubular -housmg 58.

When this hook is. in engagement with one of .sa-id lugs 56, it is carried with vthe paper carriage iuA the direction of the alrrou vat Fig. '2, that. is, to the. 4right to cause the lever 42 to swing upon its-pivot and thereby drive the. mandrel 40 nud the master wheel to the lelt at F ig., 4. As the keys 1 are operated-to write figures in the column, the master wheel 32 is correspondingly rotated in :my usual or suitable manner, to rotate the correspondingcomputing wheels 55. Then :the 'mast-er wheel has advanced past the. ci'infnpu-tinrer wheel of lowest -denomination. a cau-i (i9 formed on the hook :'15 engages n projectonO lixed 'uponfthe framework of the machine. and is thereby forced downwardly. to Withdraw the hook from :that lug 56 with which it has been in engagement. As soon as the hook is re leased, n returning spring 71 coimected to the lever l2 swings the latter in the opposite iliwetion, carrying the master wheei 32 backwardly or to -the rig-ht nt Fig. 4, that is, toward Athe computing wheel 35 of highest denomination; this movement continuing until the. hook engages the succeedi'ng lug said hook -beingprcssed up to en .ige said lug by means of the. spring 63, mi( the hook beeoi'ning fully seated in the notch '62. as at Fig. The writing of the numbers in the succeeding column Will now prnceed, an.d sa-iil number will be aecumulated on said computing wheels by the num ber wheels 39, in the manner already referred to.

When returning the carriage 6 `to begin a new line of writing, if the hook 55 is in en gagexnenl with one-'of the lugs 56, it is carried to the left at Fig. 2. until a cam edge 72 thereon strikes ast-ud' or roller 73, which may be pii/otecl upon n screw 74, threaded' into 'the top of"th`e bossfi; and by mea-ns of said roller or obstruction, the hook is cammed downwardly an'd. released from the lg 56. The spring 63y immediately lifts the hook againl and the lugs 56 in succession ride freely over a bevel or point 75 formed on the tip 'of the hook; the last I lug in the series being caught and held by the hook when thecarriage begins to 'run in letterffeeding direction.

If, during the return "of the carriage, any lug -56 strikes the hook 55 while clear of the stud 73, said ing will depress the hook 55 'by 'the bevel 75, and jump the notch 62 of the hook before 'the spring 63 can make the lug engage the n otoh. This is possible because the bevel i' 5 on its side of the notch- 62 is considerab higher 'than is the cam edge 72 on the et er side of the notch, und fthe higher bevel' throws the hook down a consilierable distance. This jumping over the notch 62 is 'almost positive beca/use the .because of imposition, to

lugT 5G fits the notehfiZ-elosely, 'to avoid -any Alost motion, und this close fitting requires 'that .the notch and lug be exactly alined Ibeffore they can engage. Y

The column Midex-or upper -compu-ting mechanism 81 which may also be desig- -neted as a subtotalizer1 in that it obtains the sub totals of each column. includes a (lrive shaft having n -bevelv pinion -83 meshing with n pinion 84 -on a shaft 85. the latter being secured to a. master wheel 86, which has spurs o1' teeth 87 to engage on internal set of teeth 88 formed -upon a series or gang of computing wheels 89, the latter mourned i-n a casing 90, and haring exterior (eetl-i 91 to mesh with gears 92 ,eanryi-ng niunber wheels 9B.

The. relative movement of the muster -wheel and the computing wheels is obtained in' this instance by connecting the casing carrying the computing` wheels, to the carriage, which may be (lone in any suitable ananhei, as by means of u latch 94, so that the easing and computing wheels move 'with the carriage relative to the master Wheel. The movable portion of the column -adder or computi-ng qnechanism can 'be supported for this movement byY means of rolls or wheels 9.5 engaging -n-supportiugra'il 95.

Since -the driving mea/ns for said shaft 82 .forms no part of tli's'inventionl it is deemed shaft, it will be understood, is rotated autel" utilize the full length of the type'writing line. It :is therefore A-neeessai'y to acti-inte the master. wheel so that it can be caught at position intermedia-te its extreme limits of movement. In this case, the return mo tiohofthe carriage is utilized togive -a pal'ssive forv 'ineffective movement; ofthe muster wheel 32. While the connection might be direct from the rri ge to the Vtotnlizer- 80, it has 'been f und onvenient ranke the connection from the subtdsalizer or column adder. -81 to the totaizer.80; This connection is preferably such that. it will be ineectivedii-ring the steplby-stepl movement of 'the carriage in i letter-feeding direction, and will be eective to the desired exlenton the l. return movement of `the'.cri'iagf J As .illustrating one form of such connecshown as being' secured to the column adder S1, a connector' 9G, which is shown in the form of a bracket secured to rails or bars 98 on the column adder 81, and provided with a tri-p 9.0 pivotally connected to the brat-.kot DT so asto lmore relative thereto in any suitable manner, as by being provided with a .stud 100 journaled in a bearing provided in a flange 101 on the bracket 9T. The trip 39, is preferably composite, so as to allow for relative movements in two directions. For this purpose it is shown as embodyinea block 102, to which the stud shaft 100 is'secured, and a latch 103 pivotally mounted on the block 102, as by being provided with an opening 101, whereby it can be journalcd on a stud shaft 105.

The trip 09 is normally heldin the position shown in Figs. S, 9 and 12, by means of a spring;r 106, which is adapted to Yper- ,mit a yielding movement in one direction, movement in the opposite direction being limited by a stop 107 provided on the trip 99, whichengages the 'under side of the bracket 97. The latch 103 is normally held.

in tbeposition shown in Figs. 8, 9 and 12, by means of 'a spring 108, which, however, permits it to. move to the position shown in Fig. 10. The action of the spring 108, in returning the latch 103,froin the position shown in Fig. to the position shown in Fig. 9. is limited by "a shoulder 109 Von the latch 103 engaging the fla-nge 101.

103 of the connector,is in a-position ready to manipulate the ward 110 or arbor shaft and the master wheel 32, on an ineffective or passive strokeott said master wheel,

for the purpose of obtaining a supplementarv reset of the master Wheel at the Ybeginning of the Writing line'.

When the master wheel hasibeen manipulated to 'a position such that it corresponds to the computing; wheels in the units col umn, the latch 103-will be engaged by a 4tripper 111, which is shown in the form of a c am,:adapted to disengage the Ylatch 103 fromA the Ward 110, by pivoting the same lagainst the tension 'of the spring 108. This permits the lever 421.0 be swung by 'thes'pring 71, so that it will tendto return the 4.nister Wheel to a position corresponding to the maximum denomination wheel in theipross computingr mechanism or'totalizer,

If, however, the initial `tabular stop 57 is located at a point corresponding to any of the other denominations of the totalizer, the hook :35 will catch on said stop, so as to previ-nt further movement' of the lever -ll and the master wheel 32, whereby said master wheel will be positioned in the denomination column desired, so that an aecu rate computation can be obtained while using the extreme left margin of the typewriting line. Y

On the step-by-steo letter-feeding movement of the carriage, the latch 103, being located to the right of the ward 110, will be permitted to snap over said ward, as in.- dicatcd in Fig. 13, by the trip pivoting on the stud shaft 100 against the tension of the spring 106, which returns it to its normal position, after it has passed the ward 110.

It will be seen that there is provided a connection between the carriage and the totalizer which moves the movable portionof the cross computing mechanism or totalizer step-by-step with the, letterlfeeding .move-- ment of the carriage, so as ,to cross add and totalize the numerals added in columns by the main adderor computing mechanism. This connection, as has been shown above, automatically resets the cross computing mechanism or totalizer before each new column or number, by thespring 71 returning.

the lever 42 untilthe hook carried thereby,

engages the next tabular stop.

Ines-much as', however, on the return i movement of the carriage after completing a line, the hook, in. disengaging from the final stop, permits the lever 42 to return the full 'distance under .the inucnce'of the master wheel', to the desired' po int, thatrs p to sav, to enable the connection between the v carriage and the totalizerto' regain accu.V

rate control of the movement of the master 'lio wheel thereby. This is accomplishel.hyV f .utilizing the return movementfof the. carringe to manipulate the master Wheel ajull ineffective or passive stroke; so that the springl can once more 'actfto return the lever 42, enabling the hook 55 to-be eaugrht by a properly located tabular stop, which operation isiattained Vthrough the.inter mediary of the connector 96-whih transmits the movement of the carriage to the movable portion 'of the cross adder or t.\talizer.

When the ronnector hasmovedthe Il'ms-- I to tend to return the master wheel thefull length off its stroke in resetting the same,

.computing mechanism which movement., however, is limited by the catching of the hook 55 by the tabular stop set at a point corresponding to the maximum denomination column of the number which it is desired to compute, at `the be 'nning of the ty ewriting line, or in the nrst column of num ers.

It will be seen that on the step-by-step movement of the' carriage, the ward 110 will be permitted to pass the connector 96' without the movement of vthe one influencing the other, b v reason of the fact that thc tripper can pivot. about theshaft 100, against'the tension of the spring 106, which will return the trippcr to its normal position.
